What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.

Spinnaker Croft 42 Skeleton

Owners widely report the Spinnaker Croft 42 Skeleton offers good build quality for its price, with some finding it a decent buy on sale. Reviewers note the 42mm case provides significant wrist presence. However, opinions are split on legibility and aesthetics, with some finding it poorly executed and uninteresting while others consider it one of the more legible skeleton watches. The watch is powered by a Seiko NH70 automatic movement with a 41-hour power reserve, though one reviewer considered the movement uninteresting. The bracelet and clasp are considered mediocre for the price point. Overall, owners and reviewers find the Spinnaker Croft 42 Skeleton to be a polarizing but potentially good value skeletonized dive watch when purchased on sale, with its build quality being a key positive for many.
